Abstract
An improved solenoid release mechanism for air dropped ordnance apparatus d the like has two pivoted jaws which are locked in closed position when the solenoid coil is energized and are spring biased to the closed position with sufficient force such that a force of about nine pounds in a downward direction will open them when the solenoid coil is not energized. An adjustment device is provided for the biasing means for each of the jaws.
Claims2
A release mechanism comprising:
- support means;
- two substantially parallel support pins mounted in spaced relationship in said support means;
- a retaining arm pivotally mounted on each of said pins;
- a stop member mounted in said support means and having a longitudinal axis parallel to the axis of said pins;
- and lying in a plane equidistant between said pins;
- said longitudinal axis being spaced from the plane containing the axis of said pins;
- said arms having complementary shaped upper free ends mating with said stop means and meeting each the other along surfaces in said plane equidistant between said pins;
- each said arm having a relieved portion along said surface between said stop and said plane containing the axis of said pins and forming, in closed position of said arms, an opening therebetween formed by semicircular surfaces adjacent said stop means and tapered surfaces and terminating in contiguous surfaces remote from said stop means and between said stop means and said plane containing the axis of said stop means;
- secondary shaped surfaces on said arms opposite the surfaces engaging said stop means and said secondary surfaces being parallel to the mating planes of said first mating surfaces;
- latching means mounted on said support and selectively movable from a normal position free of said secondary surfaces to a latching position engaging the said secondary surfaces to prevent separation as said arms;
- and
- spring means urging said arms to said closed position.
